PNEUMATIC STACKER.

SPEGITEIGA'IION forming part of Letters Patent No. 633,561, datedSeptember 26, 1899. Application filed December 30, 1,897. RenewedNovember 18, 1898. Serial No. 696,827. (No model.)

To all whom it 7771(01/00721667f7b.

Be it known that I, J OHN B. B RTHQLOM W, a citizen of the UnitedStates, residing at Peoria, in the county of Peoria and State ofIllinois, have in vented certainnew and useful Improvements in PneumaticStackers; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying draw ings, and to the letters .of reference markedthereon, which form a part of this specification.

Figure 1 is a sideelevation of a pneumatic stacking mechanism embodyingmy impro vements. Fig. 2 is atop plan view of the same. Fig. 3 is adetail View. Fig. tie a side elevation showing a slightly-modifiedconstruction. Fig. 5 is a top plan View of the parts shown in Fig. i.Fig. 6 is a side elevation of the stacker trunk or duct, constructed asshown in Fig. 1, on an enlarged scale. Fig. 7 is a transverse sectionalview taken through the duct on the line 7 f Fig. 1 and showing thesupport for the stacker-tube in rear elevation.

In the drawings, A designates the rear end of a threshing-machine, whichmay be of several styles.

A designates a vertical tube or duct by which strawand chaff from theinterior of the thresher are conducted upwardly to the dislation to thebody of the trunk, I do not believe it necessary to either illustrateor. describe in detail the construction or manner of mountingandsupporting the trunk. lt is sufficient to say that 0 indicates aperipherally-toothedriug or base, upon which the stacker-tube ismounted, and c designates a pinion for rotating said ring and tube abouta vertical axis. Suitable mechanism is provided for automaticallyreversing the direction of revolution of the pinion c at predeterminedintervals, so that the stacker-tube will be vibrated through thearc ofthe circle concentric wilh the axis of the ring 0, and at T I haveindicated one form of mechanism for elongating the discharge-trunk tocorrespond to the increase in the height of the stack.

With machines heretofore devised for utilizing a blast of air forstacking straw means have been providedfor depositing the straw atvarious points in aline extending transversely of the stack, (being theline of move ment of the outer end of the discharge trunk or tubeg) butthe result has been that the straw was deposited in a relatively narrowridge-like form, and it was necessary to manually distribute the strawto points beyond such ridge to provide a proper stack.

The object of the present invention is to provide means by which thestraw will be automatically discharged uniformly over the entire top ofthe stack.

As shownin the drawings, the hood or defiector at the outer end of thestacker-trunk consists of three telescoping sections D D D The inner ofthese sections D is rigidly secured to the tube-section B while theother two sections D D are pivotally connected together and to saidinner section at d. Short sections of chain or cable d are provided forlimiting the outward or downward movement of the sections D D relativelyto each other and to the section D. When the lower or outer section 1)of the deflector is in the position indicated in full lines in Fig. 1,for example, it will be seen that such section acts to limit the outwardmotion of the straw and to cause the same to be deposited at tube: Toeffect this automatic vertical movement of the defiector,I provide thefollowing devices: 7

Referring to that embodiment of my inven- I tion illustrated in Figs. 1,2,and 6, E designates a lever-arm which is riveted or otherwise rigidlysecured to one of the side walls of the deflector-section D and extendson opposite sides of the fulcrum or pivot d. At its upper end thislever-arm carries a guide roller or sheave e, about which extends a ropeor cable F. This rope or cable F extends around suitable guide rollersor sheaves G G, mounted, respectively, on the section B of the stacker--trunk and on the arm or standard h, extending upwardly from the bracingand supporting arm H, and has one end connected to one arm of abell-crank le verK and its other end connected to a hook-like projectionon the inclined brace-arm H. The bell-crank lever K is fulcrumed at itupon a bracket secured to one of the framing-bars L of the trunk, andthe arm of said lever is connected by alink or rod M with a sprocket N.The latter, which is mounted on a suitable shaft journaled in thestacker-trunk-supporting frame, is connected by a sprocketchain N withanother sprocket, N The latter is mounted upon a horizontal shaft n,provided also with .a bevel-pinion n, Which meshes with a bevelgear 07?,carried by a vertical shaft 71?. This shaft 'n is provided at its lowerend with a pinion n, which meshes with the teeth of a segmental rack Nrigidly and stationarily secured in position upon the framework on thethresher A and extending concentric with the ring or base 0, by whichthe stacker-trunk is horizontally vibrated.

From the above description it will be seen that as the ring or base 0 isrevolved the pinion n will be carried around the rack N and theengagement between the teeth of said pinion and rack will rotate thesprockets N N and rock the lever K about its fulcrum it. As the lowerend of the rope or cable F is fixed and held stationary, it is seen thatas the upper end of the lever K moves rearwardly in the directionindicated by the arrow the deflector-section D will be rocked upwardlyand rearwardly about its pivot at d. A coiled spring D isinterposedbetween the rear end of the lever-arm E and a'lngb on the stacker-tube,and this .spring acts to return the'deflector-section D to its originalposition as the rotation of the sprocket N causes the upper end of thelever K to move forward. The lower end of the cord or cable F ispreferably provided with a ringf, adapted to engage with either of theseries of hooklike projections h on the brace-arm H, and this lower endof such cable is within easy reach of an operator standing on the groundadjacent to the rear end of the machine A. By drawing the rope or cableF the operator may vary the i-nitialposition of the deflectorsection Dwith relation to the stacker-tube and secure the same in such positionby attaching the ringfto the proper'hook h? By connecting theautomatically-acting power devices, which actuate the deflectorrelatively to the duct, to the deflector by means of a cord or chainarranged substan tially as set forththat is to say, a cord or equivalentwhich is secured at one point to the automatic deflector-moving devicesand secured at another point to a relatively stationary holder orsupport, as to the parts at hI provide for automatically moving thedeflector relatively to the duct by the power devices and also providefor moving it by hand independently of the power devices. The operator,should he at any time see the stack taking an undesirable shape, can byhand open the deflector by drawing upon the cord, even though theautomatically-acting mechanism is at work.

It is usual to provide stacker mechanisms of this class with means foru'nclutching or throwing out of action the devices which effect thehorizontal movements of the duct. This is done to-enable the operator tostop the duct temporarily and deliver to some one part of the stack alarger quantity of straw. WVhen this is done with the mechanism hereinshown, I can still adjust the deflector by hand to deliver the straw atthe desired points, and by so arranging the parts that the cord shallhave one of its ends or fixed parts ac cessible to one standing on theground in the way illustrated every desired adjustment of the parts ofthe duct, as the movements of the hood or deflector and the adjustmentof the telescoping parts, can be accomplished from the ground andwithout requiring any climbing on the machine.

By having that part of the cord which is secured to the relativelystationary holder adjustable in the way illustratedthat is to say,constructing and arranging the parts so that more or less of the cordcan be taken up or let out-the deflector can be governed as to the partwhich it shall follow of its total possible path. Thus if it be desiredto have it move only in the lower part of its possible path the cord islengthened or let out, but if it is desired to have it move only in theupper part of its path the cord will be shortened or taken in at thefastener 1-1.. Thus provision is madefor directing the straw at timesmainly inward or toward the machine and then for directing it during adesired period mainly in a direction away from the machine.

Again, by having the other fastened part of the cord arranged to be adjusted along the vibrating lever K the throw of the deflector or thelength of the are through which it moves can be adjusted irrespective ofthe part of the path in which it may be held by theother part ofthecord. Thus at the bottom portion of the stack it is preferable tohave the power-transmitting cord secured farther away from the axis ofthe lever K, so that the vibrations of the latter will carry thedeflector over a relatively long path and deliver the straw on arelatively wide base;

but as the top of the stack is approached it can be narrowed or taperedby bringing the end of the cord nearer to the axis, and then themovement of the deflector will be in shorter paths and the straw will bedelivered over a reduced area, and by having both theseadjustments-namely, that which is attainable by having the cordadjustablyattachable to the lever at differentdistances from the axisand that whichis attainable by increasing or decreasing the total lengthof the cord-I can provide for every desired result as to the delivery ofthe straw supplemental to what are provided for by having the ductitself extensible and vertically and horizontally adjustable, and, stillfurther, it will be seen that I not only have combined with the duct andthe deflector movably mounted thereon the above-described means forefiecting the movements of the deflector by hand and at will and alsomeans for moving the said deflector by power devices which do notrequire hand actuation, but also have arranged the devices whichtransmit motion to the deflector in such way that the duct can belengthened or shortened without interference with or from suchmotion-transmitter. As shown, this is accomplished by securing the cordat one point to the power devices and at another point to a relativelystationary holder and between said points connecting it to the deflectorbyacord-guide which permits the guide to move therethrough whilemaintaining engagement, and I supplement these parts with a take-up forthe cord, which supplies idle cord when necessaryto permit extending theduct and takes up such idle cord when the ductis shortened.

In another respect the present construction is a particularlyadvantageous one for embodying my in vention-namely, in this, that thepower devices which actuate the deflector are situated at the axisaround which the duct is vertically adjusted. 'When so situated, thedistances between the driving and the driven parts can be maintainedsubstantially uniform irrespective of the horizontal or verticalposition of the duct. Of course in this respect there can be variationand the power devices can be situated otherwise; but for some reasons Iprefer that shown and here referred to.

In Figs. '1 and 5 I have illustrated a slightlymoditied construction. Inthis construction 0 designates a cylindrical or tubular rockshaftmounted in bearings 0 0 on the second duct-section B, and O designates arockshaft which is mounted in bearings 0 0 on the outer section 13 theinner end of this shaft 0 fitting within the shaft 0, so as to movelongitudinally thereof, but connected thereto to vibrate about itslongitudinal axis therewith. At its outer end the shaft 0 is providedwith a crank-arm 0 to the free end of which is connected a shortchain-section 0 the lower end of which may be engaged with either of aseries of apertures d, formed in a bar 61 secured to thedeflector-section D To the rock-shaft 0, near the inner end thereof, isconnected a crank-arm 0 the free end of which is connected to one end ofa link P, the other end of which is connected to the sprocket N. It willbe seen that as the sprocket N is rotated in the manner hereinbefore described the link P and crank O will'cause the compound rockshaft 0 O tovibrate about its longitudinal axis, and the upward movement of thecrank O at the outer end of said shaft will act to raise thedeflectorsection D As the revolution of the sprocket N brings the partsP O 0 into their origi= nal positions the weight of the section D willcause it to move downwardly about its pivot at d.

Any suitable power devices may be provided for driving the pinion c. Inthe drawings I have illustrated, more or less conventionally, a train ofgearing connecting said pinion with a band-wheel U, mounted on thethresher A.

At V is indicated the casing of the fan or ejector, by which thestraw-moving blast of air is created, said casing communicating with theuptake-duct A.

From the above description and the drawings it will be seen that as thestacker tube or trunk is rotated about the vertical axis of thecylindrical base 0 the deflector at the outer end of such duct will beautomatically vibrated about its pivot and thestraw escaping from thesection B will be guided to points relatively nearer or farther from theouter end of the duct on a line transverse to that of the horizontalmovement of such end, so that the straw will be uniformly distributedover the entire top of the stack.

However, I do not herein claim, the specific matters incident to theconstruction shown in Figs. 4 and 5, having made these the subject ofclaims in another application filed by me-to wit, Serial No. 696,875,filed November 26, 189S-but herein call attention to the constructionillustrated in said figures and last above described, inasmuch as itshows the fact that many features of my invention can be readilyembodied in numerous forms of mechanism.
